One assumes then that Mrs Berek did not accompany you ~ or she could have changed it. ![whistle:](https://www.virtual-pub.com/SMF/Smileys/default/whistling.gif)
she doesnt even know where the petrol cap is
Well, knowledge of the whereabouts of the petrol cap is hardly going to help in changing a wheel is it?
I hardly think either you/she/the AA man will change a TYRE at the roadside - a wheel maybe, but a TYRE - no way (though they do for big articulated trucks but I doubt Berek was in one of those!)
